my only criteria is that the music is good and not bad, idgaf about genre. ive been wanting to listen to some nice technical guitar work lately. list is some favs of mine, relate recs to them or don't idc

Polyphia - Muse, or Inspire
Save Us From The Archon - L'Eclisse
The User Lives - Valkyr
Angel Vivaldi - Universal Language
Within The Ruins - Creature (They kind of suck now, but this album is tits for guitar work)

Steve Howe is one of rock's great guitarists. I would listen to The Yes Album, Fragile and Close to the Edge.

Alex Lifeson is also a solid player. Hemispheres, Permanent Waves and Moving Pictures are at the top of my Rush list.

Since you like Radiohead and Talk Talk, you might like later King Crimson: I would listen to Discipline and Three of a Perfect Pair.

If you want to learn fingerstyle, then Willy Porter is the best guitarist you've never heard -- he had a semi-hit in the mid-90s, but then never quite made it. His album Falling Forward is a good one -- this acoustic version of a song from that album shows what a good player he is: https://www.youtube.com/watch?v=ZRgU5kNDanw (It's a promo video for Guild guitars -- the song starts at 0:39.)
